Abstract

Logical thinking serves as the backbone of understanding mathematics which helps learners to connect concepts, justify methods, and construct meaningful explanation. Many students acquire procedural competence to solve a mathematical problem but they remain unable to clearly explain the reasoning that justifies each mathematical step. This gap between performing mathematical problem and explaining solutions undermines conceptual understanding and hinders the development of higher-order reasoning abilities. This research paper addresses this issue by presenting a structured pathway for rebuilding a clear and structured logical framework for mathematics learning. This proposed framework emphasizes on deliberately integration of symbolic logic and formal inference rules into regular mathematical pedagogy. The explicit incorporation of logic within problem-solving practices helps learners to move beyond intuitive thinking toward well-justified reasoning. In support of this objective, this study presents three interrelated approaches: Reasoning Reconstruction Model (RRM), Step–Reason Mapping (SRM) and Logic-Integrated Mathematical Expression (LIME). Together, these approaches support students in structuring their thinking, aligning each solution step to logical rules and rebuilding coherent mathematical arguments.

Abstract

Developing students’ higher-order thinking skills (HOTS) is a critical goal in mathematics education, as it enables learners to analyze, evaluate, and create solutions to complex problems. This study aimed to assess the effectiveness of Project-Based Learning (PjBL) in enhancing HOTS among secondary school students at Sekolah Menengah Chung Hwa, Brunei Darussalam. A mixed-methods approach was employed, combining quantitative and qualitative data. The study involved 60 students from grade 10, who participated in mathematics projects designed to promote critical thinking, problem-solving, and creative reasoning over a six-week period. Data collection included pre- and post-tests measuring HOTS, classroom observations, and student interviews to explore experiences and perceptions of PjBL. The quantitative results indicated a significant increase in HOTS scores after the intervention, with the average post-test score rising from 62.5 to 81.3. Qualitative analysis revealed that students were more engaged, collaborative, and reflective during the project activities, demonstrating the ability to apply mathematical concepts in real-world contexts. These findings suggest that integrating PjBL in mathematics instruction not only improves students’ cognitive skills but also fosters motivation and deeper understanding. The study highlights the potential of active, student-centered learning approaches to cultivate essential skills for the 21st century. Implications for curriculum design, teacher training, and future research on enhancing HOTS in mathematics are discussed.

Abstract

Mathematics education, particularly in the domain of three-dimensional geometry, often demands high-level spatial visualization skills, posing a significant cognitive barrier for many secondary students. Conventional teaching methods relying on two-dimensional representations are frequently insufficient to elucidate spatial complexities. Augmented Reality (AR) technology offers an innovative pedagogical solution by projecting virtual objects into the real environment, bridging the gap between abstract representations and concrete understanding. This study aims to empirically evaluate the effectiveness of AR-supported learning on geometry conceptual mastery among students at Nanyang Girls' High School. The research employed a quasi-experimental design with pre-test and post-test measures on non-equivalent control groups. Participants comprised secondary level students divided into two groups: an experimental group utilizing AR applications to interactively visualize, manipulate, and dissect geometric solids, and a control group using traditional text-and-image-based learning media. Assessment instruments focused on deep conceptual understanding of solid properties, geometric transformations, and spatial relationships. Statistical analysis revealed a significant difference in the mean post-test score improvement of the experimental group compared to the control group ($p < 0.05$). These findings indicate that the interactive visualization features offered by AR effectively assist students in constructing more accurate mental models and achieving stronger memory retention of complex geometric objects. Beyond cognitive gains, qualitative data also noted increased student motivation and active engagement during the exploration process. This study concludes that AR integration is a valid instructional strategy for enhancing geometry mastery and recommends the development of mathematics curricula that are more adaptive to immersive technologies at the secondary level.

Abstract

Statistical literacy has become an essential competence in secondary education due to its critical role in data-driven decision-making. This study aims to examine the effect of collaborative learning on students’ statistical literacy at Sekolah Menengah Pengiran Anak Puteri Hajah Masna, Brunei Darussalam. A quasi-experimental design with pre-test and post-test was employed, involving an experimental group exposed to collaborative learning strategies and a control group taught using conventional methods. The sample comprised 60 upper secondary students selected through purposive sampling. Data were collected using a validated statistical literacy test and analyzed using paired and independent t-tests to assess significant differences between groups. Findings indicate that students participating in collaborative learning demonstrated significantly higher gains in statistical literacy compared to their peers in the control group. Specifically, collaborative learning enhanced students’ ability to understand statistical concepts, analyze data, interpret graphs, and solve statistical problems effectively. These results suggest that collaborative learning provides a conducive environment for fostering analytical thinking and practical application of statistical knowledge. The study recommends the systematic implementation of collaborative learning strategies within the mathematics curriculum to promote statistical literacy at the secondary level. Furthermore, this research highlights the potential for further studies exploring the impact of collaborative approaches on numerical literacy and critical thinking skills in broader educational contexts. Overall, collaborative learning emerges as a viable pedagogical approach for developing competent, data-literate students capable of navigating an increasingly information-driven world.

Abstract

This study aims to examine the effectiveness of the Realistic Mathematics Education (RME) approach in enhancing students’ numeracy skills at Sekolah Kebangsaan Seri Suria. Numeracy is a fundamental competence that supports students’ ability to apply mathematical concepts in real-life contexts; however, many primary school students experience difficulties in connecting abstract mathematical ideas to everyday situations. To address this issue, a quasi-experimental design with a pre-test and post-test control group was employed. The participants consisted of 60 Year 5 students divided into an experimental group receiving instruction through the RME approach and a control group taught using conventional methods. Data were collected through standardized numeracy tests and classroom observation sheets. The results indicated a statistically significant improvement in the experimental group’s post-test scores compared to the control group. Students exposed to RME demonstrated better conceptual understanding, problem-solving abilities, and engagement during learning activities. The findings suggest that contextual learning tasks, student-centered exploration, and guided reinvention processes embedded in the RME framework contribute positively to numeracy development. This study highlights the importance of integrating realistic contexts into mathematics instruction to foster meaningful learning experiences. It is recommended that primary school teachers adopt RME strategies to strengthen numeracy proficiency and promote deeper mathematical understanding among learners.
